The amount of leverage you use will depend on your broker and what you feel comfortable with. Typically, the broker will require a deposit, also known as “margin“. Once you have deposited your money, you will then be able to trade. The broker will also specify how much margin is required per position (lot) traded. For example, if the allowed leverage is 100:1 (or 1% of position required), and you wanted to trade a position worth $100,000, but you only have $5,000 in your account. No problem as your broker would set aside $1,000 as a deposit and let you “borrow” the rest. Of course, any losses or gains will be deducted or added to the remaining cash balance in your account. The minimum security (margin) for each lot will vary from broker to broker. In the example above, the broker required a 1% margin. This means that for every $100,000 traded, the broker wants $1,000 as a deposit on the position.
